Is this a function?
Yes, it is a function because none of the x-values repeat.
Evaluate the following function for f(-2)
f(x) = 5x^3+6x^2+4x
What is the domain of the following set of values:
{-9, -6, 3, 12, 20}

The vertex is at (2,-2) and it is a minimum.
Finish the end behavior for the graph below:
As x -> \infty, y ->
\infty
Is this a function?
No, it is not a function, the x-value 3 repeats/is used twice.

g(x)=x^2/(2x)
g(-16) = -8

Is it a function? Explain your answer.
Yes, it is a function because none of the x-values are repeated.

Choose all of the graphs with
the following end behavior:
as x-> -\infty, y -> infty
B and D
Is this graph a function? Explain.
This graph is not a function because:
- it does not pass the vertical line test
- there is more than 1 point on some x-values
- x-values are repeated.
